The group of inventions is the relative the plant with in-cell mixing, for example, such as a gas turbine; an internal combustion engine with direct intake gas fuel into the cylinder (with the induced ignition); engines with external heat supply (for example, operating on the Stirling cycle) with mixing by means of the air-fuel nozzles in the heating chamber and others. In the particular case, the group of inventions relates to a device for storage of solid hydrocarbon fuel used in such systems. The most effective group of inventions can be applied to power plants, placed on vehicles, such as cars, light aircraft, boats, etc.

Known systems supply gaseous fuel power plant comprising a tank filled with hydrocarbon fuel. In this system the tank filled hydrocarbon fuel, combined into one unit with a reactor that has a connection line formed in the reactor the gaseous fuel with the consumer - internal combustion engine (see RF patent N 2059845 in class. F 02 B 43/10 1994). This gaseous fuel is additional to the liquid fuel stored in a separate tank.

In this system, technical re Romadka and complex, therefore its placement on the vehicle is very inefficient.

Known systems supply gaseous fuel power plant comprising a tank filled solid hydrocarbon fuel, is connected through a screw feeder with pyrolytic reactor connected at the output to the consumer of the gas turbine (see European patent N 0591703 in class. F 02 C 3/28 for 1993).

In this system, a solid hydrocarbon fuel is a polymer waste type crushed plastic containers, discarded plastic bags and bottles, etc. that assumes their chemical composition of impurities (for example, in the articles of low - pressure polyethylene heavy metals). All this involves the use of special filter elements to clean the gaseous fuel at the entrance to the power plant (gas turbine). Thus, the geometry of waste polymer waste excludes the implementation of the compact container (hopper) and makes it impossible to standardize the storage system polymer fuel that significantly interferes with the implementation of such system power solid hydrocarbon fuel in vehicles.

In Fig. 2 schematically shows the device described for the storage and supply of fuel, a view in plan, in a variant, when 3/4 of the body is cylindrical, and one quarter are in the form of a corner section of the box.

The power supply system of the power plant gaseous fuels obtained in the pyrolysis of solid hydrocarbons (polymer) fuel, contains the cartridge 1 with the polymer tape 2 inside, mostly plastic. Tape can also be made of polypropylene and other known polymeric materials, transportiruyushchie in the process of pyrolysis of low molecular weight gaseous hydrocarbons (ethylene, propylene, methane, propane, and some such). The cartridge 1 through the spout 3 are connected to the tape 2 with pyrolytic reactor 4. Reactor 4 is made in the form of insulated by a lining 5 shell-and-tube apparatus with at least one pipe 6 represents a reaction zone that is connected at the inlet to the evaporator chamber 7 transition solid polymer fuel 2 in the form of a tape in the vapor phase. Outlet pipe 6 (number of tubes 6 is determined necessary getproposal ability reactor 4) connected to the quenching chamber 8 which is connected through a filter 9 to the discharge line 10 leading to the consumer (for example, to the heating chamber 11 of the gas turbine 12). Mitrophanov another type).

Pipe 6 (reactor area) can be filled with a heterogeneous catalyst (when catalytic pyrolysis), such as mordenite, modified Nickel (20%) amorphous aluminosilicate 15.

Evaporation chamber 7 is equipped with a heater 16 (e.g., Ten), electrically connected to the battery 17. While on the casing 18 of the reactor 4 is equipped with a gas burner 19, the United gas line 20 with the release of the quenching chamber 8. In the lining 5, insulating the evaporator chamber 7, the slot 21 for tape 2, provided with a seal in the form of a liquid shutter 22, and the viscous sealing liquid is actually polymer melt 23. The quenching chamber 8 is a double chamber unit, single cavity (for example, in the form of tubes 24) are the products of pyrolysis of the pipe 6, while the other (annulus 25) circulates the cooling water flowing through the line 26 to the heat sink 27. On the discharge line 10 is provided gas fuel compressor 28, the fuel injection throttle 29 and the receiver 30 to the limited amount for a short period of accumulation of gas fuel (pyrogas).

As the heat sink 27 may be used radiator m and direct intake gas fuel into the cylinders or, for example, when connected to the system being described gas fuel power Stirling engine).

Solid fuel (polymer tape 2) by means of a metering device 3 through the slot 21 is supplied into the evaporation chamber 7 of the reactor 4, and the slot 21 is sealed with a liquid shutter 22 in the form of a viscous polymer melt 23, enveloping the tape 2 on the inner junction of the slots 21. After evaporation of the (partial decomposition of polymer molecules, 2) the resulting hydrocarbon steam gas enters the reaction zone 15 of the pipe 6, the temperature of which length is maintained relatively constant. In the case of thermal pyrolysis she should not be below 800oC. During catalytic pyrolysis, due to the presence in the reaction zone 15 fine heterogeneous catalyst process will take place in a softer mode (T 650oC). The process from 0.05 to 0.3 sec depending on the geometry of the reaction zone 15. (During catalytic pyrolysis highly desirable additive in the area 15 of the water vapor is thinner in proportion to the sin 1/1 in order to inhibit the process of coking reaction zone 15. In this case, the resource of the catalyst to the required procedures for the removal of coke will be from 1.5 to 3 thousand hours). In the reaction zone 15 when Yasuko molecules of the hydrocarbon polymer and the formation of gaseous products (ethylene, propylene, methane and others). Then the sin leaves the reaction zone 15 of the pipe 6 and flows into the quenching chamber 8, where in a tubular heat exchanger 24, the cooled water from the radiator 27 through line 26 into the space 25 within the time interval of not more than 0,03 with its temperature drops to 350oC that makes the process of formation of low molecular weight gaseous hydrocarbons irreversible. In the pyrolysis process takes the amount of heat that does not exceed 10-12% of the calories of hydrocarbon fuel. However, the exhaust gases of various power units, in particular a gas turbine 12, the incoming line 14 in the annular space 13 of the reactor 4, have not sufficiently high temperature, so as to ensure a steady flow of the pyrolysis process, it is necessary to make an additional heating pipes 6 by burning part of the pyrogas incoming gas line 20 to the gas burners 19 arranged on the casing 18 of the reactor 4. Obviously, while 5-7% increases fuel consumption, power device (gas turbine 12). (Eventually these fuel losses associated with efficiency gas burners 19 and the insulation 5 of the reactor 4). Chilled sin postopia IMY from the power device, where through the gas fuel regulator 29 of the power device under excessive pressure enters the heating chamber 11 of the gas turbine 12. In order to ensure the necessary abrupt increase in capacity (for example, when overtaking, taking a vehicle) into the combustion chamber of the power plant receives an additional portion of the gas fuel from the receiver 30. Run the power plant is carried out by pre-heating the evaporation chamber 7, to a temperature which provides the initial formation of the products of the combined-cycle decomposition of the liquid phase 23. Starting heating provide heating Elements 16, the power which is supplied from the battery 17. Products combined-cycle decomposition is coming through the pipes 16 and line 20 to the gas burners 19, which thus provide the starting heating of the pyrolysis reactor 4 and the subsequent starting of the power plant. It is also possible that the use of the starting portion of gas from the receiver 30.
